SEAT'OR STAGE FOR WINDO W-CLEAN ERS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 683,013, datedSeptember 24, 1991.

Application filed June 29, 1901.

To all whom it may concern: I

Be it known that we, THOMAS ALLDER, the

. younger, builder and decorator, residing at 7 J erdan Place, Fulham,and THOMAS HEWER STREATER, window-cleaning contractor, residing at 90Hazlebury road, Fulham, Lon- 'don, in the county of London, England,have invented a certain new and useful Improved Seat or Stage forWindow-Cleaners or the Like; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The object of the present invention is to provide a light and portableseat or stage for window cleaners and the like adapted to be detachablysecured to a window-sill and to accommodate the user in either a sittingor a standing position, he being in either case inclosed on three sidesand so protected against all risk of accident. Adjustments are providedfor adapting the device for attachment to window-sills of varyingdimensions, and when not required for use the apparatus may be foldedtogether and compactly stowed away.

Our invention will be better understood on referring to the annexeddrawings, wherein Figure 1 is a side elevation of the invention. Fig. 2is a plan thereof, and Figs. 3 and 4 are details.

A A are a pair of brackets or cantalivers, whereof the vertical sides aare furnished with studs or pins 1), Fig. 3, which enter cor respondingholes 0, formed in a fillet d, Fig. at, which is preferably of wood andsecured to the front of the wood sill or sash frame 6 by nails orscrews. This fillet is so fixed that when the studs 1) are in place thelower surfaces of the brackets 01' cantalivers or feet f, provided orformed thereon, will bear on the stone sill :g inside the line of thesupportingbrickwork. The said feet should not bear on the overhang ofthe sill, as the same might possibly give way. Each cantaliver orbracket A has an extension or arm A", which projects through the Windowinto the room and carries a slide h, adjustable longitudinally thereofand fixed by a thumb-screw-h. Trav- Serial No. 66,506. (No model.)

The said rod between its bearings traversing a claw or clamp Z, whichpasses through a-vertical slot in the bracket-piece aforesaid, and isthereby prevented from rotating with the screwthreaded rod 2' when thelatter is revolved by the regulating-note" to effect the vertical ad justment of the said claw, which engages with the under side of thenosing an inside 'the window-frame or with a projection there provided.The brackets A having been fixed in position by slipping their studs binto the fillet-holes c and then adjusting the claws Z to engage beneaththe nosing m may be finally tightened as an additional security byscrewing down the tightening-screws 'n, which pass through the arms Aand bear upon the sash-frame.

B is the seat, which is supported upon the oantalivers A and has in theunder side holes entered by the studs 0 on the brackets. Lifting of thefront of the seat is prevented by slipping it under the hooks or clipspon the brackets, and as an additional security stoppieces 19 may be alsofixed to the brackets to engage the rear edge of the seat. Hinged to thelatter is the back 0, which is divided horizontally and hinged along theline of division, so that the upper portion 0 may be folded back, asindicated by the dotted lines, Fig. 1, when the device is to be used bya person in a sitting posture.

D D are uprights pivoted to the brackets A at q, and E E are armspivoted to said uprights and formed with hooks at their other too of theuprights D lever against the brackets A behind the studs b. To preventthe said uprights from being inadvertently thrust forward against thewindow, a tie-bar F is provided on each side, pivoted to the bracketA att and engaging with its hooked enda stud u on the upright D. The tumblers is preferably fixed to the pivot of the arm E and the arm and pivotmade to move together, so that in order to engage the hooked end of thetiebarF with its stud u the arm E is first raised,

-thereby moving the tumbler 8' out of the clean ers, but also forpainters and the like.

What we claim, and desire to secure by Letters Patent of the UnitedStates, is-.

1. A device for the purpose set forth, comprising brackets adapted to bedetachablysecured to a window-sill, a seat carried by the brackets, aback hinged thereto, uprights hinged or pivoted to the brackets, meansfor preventing the collapse of the uprights when extended and arms orside guards detachably connecting said uprights with the back so as tosupport the latter, substantially as described.

2. In a device for the purpose set forth, the combination of a pair ofbrackets or supports adapted to be detachably secured to a window-sill,a seat supported by said brackets, a back hinged to the seat and dividedand hinged horizontally so that the upper portion may be folded down,uprights attached to the brackets, and arms or side guards detachablyconnecting said uprights with the upper and lower portions respectivelyof the back so as to support the same, substantially as described andillustrated.

3. In a device for the purpose set forth, the combination with bracketsadapted to be detachably secured to a window-sill, of a seat supportedon said brackets a back hinged thereto and divided and hingedhorizontally, uprights hinged or pivoted to the brackets anddetachablyconnected by swing-arms or side guards with the two portions of theback, and tie-bars detachably connecting the uprights when extended withthe brackets, substantially as described.
